MACHINE Foncum-rive BRA-BS,-

To all-whom it ma'yrconcemt'r Be it knownthatI, ,I'IENRY' VVATERMAN, of the city, county, and State ofaNew York, machinist, have invented, made, and applied to use certainnew, and useful improvements in the application; arrangement,- and combination of well-known mechanical means in common use, with thosenot-rbefore so used for the purpose of: cutting. nails of any description from hoop'orplate ironi, the intent of such new arrangement being to cut nails with a point somewhat of a bluntchisel form and to give a shoulder on each side of'the head by the cutters, thereby producing a-nail that willenter easily and drive and hold well, such-mode of cutting being mostly applicable to that sort of nails called brads, for which improvements I seek Letters Patentofthe- United States;

and that the mode ofconstructing. and using" said improvements are fullyset'forth and shown in the following description and in the drawings, attached to a and making part of this specification-, -where1n= j v Figure 1 is a horizontal plan, Eig-HZjis'an elevation of the machine as inuse, Fig.1 3 is a vertical sectional elevation of-the back end, and Fig. 4 is asimilarelevation'of the fore end of the machine. is Such separate figures as are neededare separately explained and" the; letters and numbers used as marksof reference i apply to the same parts in all the several figures.- 71 j V. A, A are the side frames on which the working pa-rtsa-re' mounted.

At the side A on the small standard of the wheel 0, a pair of lugs 76, receive the centerscrews Z, Z, which carry a long arm m, this arm at n is jointed to a cross lever 0, which is made in two parts with a slot and screws 79 to adjust the length on this end, the end on the side A being jointed in a slot to the to regula-teasmall'slide piece u within the slot in the frame t," made with a smallelbow which-elbow is in contact-with a set screw of in a" small lug-on the'fore'end of'the frame tand the fore end of the piece 24 receivesthe tang of a long gage springxw Vmade' to slip into the fore ends of theframe z: and slide piece -10 and to. be" regulated lengthwise by: the set screws-o and 12 and the spring-w overlies the bell crank barit and cross lever 0, on'this lastapair of studs m, 00, come up on-each side of thegage-spring w, and regulate the lateral motion given 1 to it, the spring w finishes iIf-a curved-up and somewhat round edged chisel end under them'oving cutt'ersor chops, the spring 0 being-given to keepit always up to'the underedge of the top cutters andto rise fallwith thena at I each vibration; and I thus regulates-the Width ofthe nailwhen rcut-' lllflg'tlS hereafter described, this gage spring w and its carrierframe a are shown separate: in the detached Figs 5 and "6, the long armrm finishes with an elbow 3 upward-Lat the front of-themachi nefor use as-hereafter described. I On the crank cam of the shaft a is a strong. connecting bar 2, the fore-end -of V which is knuckle jointed at a to thecutti block D, which is mounted on-short centers b in t-he head b-lock' E, these lIElV8.-Etl3 each enda bracket 0 on thehead-blockanda p set screw d to-regulate the place of the cutter block-.- Within the cutter block-- are thetwo cutters e bedded on across piecev 7- at the back having a-set=screw to each cu-tter,- and in front area 'pa-ir ofbfosses g 9 which areggrooved down the front to receivethe tenons of the front keeper h, having 'two' setscre'ws i 6?, in front of the cutters and a set screw on each side regulates the cutters laterally. On the inner end of each boss 9 is a crooked guide bar 70 I0 the inside ofv the lower curve on each of these operates on the outside shoulders of two crooked vertical springs Z Z whose lower ends are secured inside the head block in front of'the lower and fixed cutter m the tops are made each witha small shoulder overlapping the edge ofthe cutter; these guide bars and springs are so regulated that they direct the material laterallyas it enters to be cut as hereafter described, and the positions and forms of these guide bars and springs are shown in detached skeleton'section in the large sized Fig. 7 The lower cutter m is set into a mortise or hollow in thehead block and is regulated by set'screws behind and in front. on each side and "below and the two upper cutters are counteredged tofit the form of the edge on the lower cutter as shown in the detached Fig.10, this forms'the heads and points of the nails as described hereafter.

- The elbow y on the side arm m already noticed entersa hole in a sliding crossxplate n which moves with the arm acrossthe front of the cutters'andis'jointed to and carries withit that end of the metal trough 'o ,'which is to be made of a width to receive the metal from which the nails are to be cut according to the size-of the intended nail ally and "as the metal istobe cut hot the;

Figs. 8 and 9 represent-a pair of wide chopped pincersiwit-h one arm fitted 'onra plate to slide 'on' the bottom of the trough 0 by thistoolthe workman can handle and V laterally underthe cutters, substantially as pushonany piece however-hot or shortjn length, 'so as to cut up the material without waste. V

The edges of the cutters are to be counter" formed as shown in the detached Fig. 10, to

form the nails as described in the mode for working this machine which is as follows:

i The -gage [spring bar L0,' is to be regulated r by. the set screws 1),.and o at a-..c 1istance I back from the edgeof the lower cutter m that will give a nail of the desired width the guidebars 6 ,10 and shouldered spring Z Z properly adjusted and the center 32?, of the feeding trough 0 adjustedinearei to, or farther from the cutters so as to give the requiredtaper to the nail.

' thickness heated to a low red heat, and holding it atone end by the pincers, Figs. 8 g

The workman is then to take metal of the proper'width and V 7 well known."

used as Iuse the same: a

and '9, placeit inthe trougho and push the other end against the cutters and motion being given to the machine by a band from the drum B','to any competent power each erally by the guide bars Z0 X0 and the'sho-uldered. springs Z ,1[Z and stopped by the chisel end of'the spring gage w, the top cutter'asit jdescends will cut off a'nail in the form of the Fig. 11, which will drive easilyand hold well. If the lateral motion given to the feedingtrough 0 should be a little m'orethan neededthe springs r, 1', on'

the sideof the arm 9 will yield as the a crooked guidebars "70 .79 come; down to adjust the position of the shouldered springs Z Z and allow the 'metalfto be entered as they guideit, so'asto' form the'nails alike.

It will be evident to those acquainted with such machinery that the same means are equally applicable to out brad nails of other 'metals than iron, and-that changing the cutters' to havethe cutting part in 'the form shown in Fig. 12, will produce brad nails .with one shoulder to the headinstead of two.

I do not claim asmy invention the form of anyof theabove parts, as they are mostly I therefore claim as new and not before 1;. The. vibrating spring gage w, to

regulate the width of the nails when cutting sub stantiallya's the same isidescribed. V

turning the'metal over substantially asthe same are. herein set forth.

Inwitness whereofIhave hereunto set my handfin'the city of jNew" York this seventeenth day? of July in theyear one thousand eight hundred and thirty nineand in the presence of the witnesses.- v, V p Q: HENRY WATERMAN.
